The utility model discloses a kind of anchor rod cable stress sensors of being convenient for connection and fixed, including sensor body and bottom mat, the outside middle part of sensor body is equipped with transmission line, bottom mat is installed below sensor body, and high-strength shaft is installed in the left side of bottom mat, the below high-strength shaft is equipped with rotary plate, and rotary plate and high-strength shaft are rotationally connected.This kind of anchor rod cable stress sensor of being convenient for connection and fixed, compared with the existing anchor rod cable stress sensor, four groups of positioning components are convenient for the installation and fixation of bottom mat and top mat, and the axis is aligned, rotating stud drives two slide rails to slide in rotary plate, wedge block moves and jolts rotary plate, rotary plate changes angle by high-strength shaft rotation, so that the axis of sensor body and anchor rod axis are aligned, the data measured by sensor body is more accurate, two nuts are clamped by gasket at the junction of stud and slide rail, prevent loosening and cause wedge block to move and change angle, installation is more stable.

The preparation method of the carbon material catalytic electrode material provided by the present invention can form a core-shell structure in which the core is a metal-N-doped carbon core with a low surface work function and the shell is a MAX semiconducting phase, the core or small microsphere inside the core-shell structure has a low surface work function, forming a high catalytic carbon core, and can prevent the direct contact between the catalytic carbon core and the electrolyte, greatly reducing the shedding of metal-doped atoms and the occurrence of side reactions, the outer polymer large microsphere inherits the topological structure of the phenolic-phenolic amine-pyrrole polymer, can effectively regulate the carbonization reaction process of the conjugated skeleton, and the side chain carbon formed while the shell directly constructs a developed pore structure can further selectively adsorb and desorb the reactant, greatly improving the catalytic efficiency of the electrocatalytic material. Thereby, the catalytic electrode material finally prepared produces a large current density and a high Faraday efficiency at a low overpotential, and can ensure that the catalytic electrode material has high mechanical strength.

The utility model relates to the field of jewelry processing, and discloses a jewelry design clamping device with a dust cleaning function, which comprises a base, two groups of side plates are internally and rotatably connected with a driving shaft, the other ends of two groups of connecting discs are connected with a fixed seat, and the surface of the circumference of the fixed seat is provided with a plurality of groups of grooves; clamping assemblies are arranged in the multiple sets of grooves, a connecting rod is installed at the top of one set of side plates, a second connecting lug is installed at the bottom end of the inner side of the connecting rod, a sweeping rod is rotationally connected into the second connecting lug, and bristles are installed at the bottom of the sweeping rod. According to the jewelry cleaning device, multiple sets of jewelry can be clamped and fixed through the fixing base, the groove and the clamping assembly, the jewelry with different diameters can be clamped, the application range of the device is widened, dust on the surfaces of the jewelry can be cleaned through a cleaning rod, bristles and a second connecting lug, the dust on the surfaces of the jewelry can be effectively removed, and the quality of the jewelry is improved.

The utility model relates to the technical field of new energy automobiles, in particular to an interconnection USB (Universal Serial Bus), which comprises a male seat and a female seat, the male seat comprises a plug, a male line, a bracket and an elastic piece, the plug is connected with the male line, the male line is connected with the bracket, the bracket is provided with an accommodating cavity for accommodating the plug, and the elastic piece is arranged in the accommodating cavity. The elastic piece is connected with the support and extends into the containing cavity, the female seat comprises a socket, a bus and a connecting pipe, the socket is connected with the bus, the bus is connected with the connecting pipe, and the connecting pipe is connected with the containing cavity in an inserted mode and provided with a groove connected with the elastic piece in a clamped mode. According to the interconnection USB provided by the utility model, the elastic piece of the male seat is clamped with the groove of the connecting pipe of the female seat, so that the connection stability of the male seat and the female seat is improved, and the condition that the male seat and the female seat are separated due to bumping and vibration can be effectively reduced, thereby achieving the purpose of improving the contact stability of the interconnection USB installed on a new energy automobile.

The utility model provides gold jewelry inlaid with gemstones. The gold jewelry comprises a jewelry body, an outer frame body, the gemstones and a hard gold electroplated layer, the outer surface of the jewelry body is made of hard gold, so that the overall hardness of the jewelry can be improved, and deformation is avoided. The outer frame body is sleeved and matched with the outer side of the jewelry body, and a plurality of embedding positions are arranged on the outer frame body in a hollowed-out manner; by arranging the outer frame body independent of the jewelry body, the processing difficulty of the inlaying position is reduced, and gem inlaying is facilitated. The gemstone, the outer frame body and the body are combined into a whole by utilizing an electroplating process, so that the outer surfaces of the gemstone, the outer frame body and the body are covered with a hard gold electroplating layer which is connected into a whole, the structural strength is enhanced, and the gemstone is effectively prevented from falling off. According to the scheme, the inlaying problem caused by hard pure gold brittleness is solved, and glue is not needed. The electroplated layer is used for integrated covering, so that gemstone falling is avoided, and durability is improved; the outer frame body can be independently processed, so that the production efficiency and the design flexibility are improved.
